Delia reminds Ash about how much she loves him and gives him a kiss on the forehead. Ash shrugs this off by getting mad at Delia, then cries again. On the ride home, the two of them were in silence, both not wanting to talk to each other until when they arrive home, Delia knocks on Ash's door to mention that it wasn't his fault.
Ash responds by crying and saying it wasn't his fault and then everyone started laughing at Ash (one kid even uploaded a video of him crying to YouTube). The entire airport noticed what Ash did, then Delia decided to yell at Ash for what he did. She bribed the clerk for her tickets when finally Ash let it loose. The two of them then arrive at the airport where their clerk was being very sarcastic, and Delia didn't approve of that. Ash decides to go to Alola and brings his mom along the way but only if she doesn't embarrass Ash.
The movie begins where Ash Ketchum arrives home to his mother, Delia, saying his memories of Kalos over a cup of hot cocoa. Is the power enough, or does Ash have to travel back to Kanto? One night, he receives a surprise encounter from Tapu Koko, giving his Pikachu lots of power. Ash Ketchum still dreams of being the greatest Pokemon master, and now he has to fulfill his dream in Alola! During when he is in the Alolan School, he makes new friends (and enemies) and travels through Alola to compete in Island Trials to earn Z-Crystals.
